Abstract: PURPOSE:To obtain the titled compound, containing a novel compound of the same system as the naturally occurring compound and having antimicrobial activity in a large amount by the chemical synthetic method in one stage, by oxidizing 2-(2-hydroxyphenyl)-2,5-dihydrofuran with a specific oxidizing agent. CONSTITUTION:A 2-(2-hydroxyphenyl)-2,5-dihydrofuran (in which 4-methyl substitution product thereof is a well-known compound) is reacted with n-butyl lithium and converted into a metal salt, e.g. lithium salt, to increase the solubility in water. The resultant metal salt then oxidized with an oxidizing agent, e.g. an aqueous solution of potassium nitrosodisulfonate (called Fremy's salt) to afford the aimed compound, capable of existing stably at <=0 deg.C in N2 though decomposed by allowing to stand at room temperature and useful as a medicine, e.g. 2-quinoyl-4-(4-methyl-3-pentenyl)furan, particularly a 2-quinoyl-4-substituted furan. EFFECT:The raw material can also be readily synthesized.

Abstract: PURPOSE: To simplify the copying operation as well as avoid leaving the original on the copying device, by securing an automatic control to the opening/closing of the original holder in coupling to the operation of the copy button.  
     CONSTITUTION: The lever 17 is provided in the main body 11 of the copying device with one end of the lever fixed to the side steel plate 13a at the end of the base of the original holder 13. And one end 18a of the belt 18 is attached to the other end of the lever 17, and the other end 18b of the belt 18 is stuck to the fringe of the circular finger plate 19. The plate 19 is usually at the position shown in the figure and then lifts up the holder 13 to then stop the holder at the position in the figure. The plate 19 has a coupled action with the copy button 15 and potates in the direction of the arrow centering on the center shaft 20 and with push of the button 15. The plate 19 continues the rotating motion until it falls flat onto the stage glass 12 to give an automatic holding to the original 21. When the copying action is over, the plate 19 rotates 180° round the shaft 20 to put the holder 13 back to the original position.

Filed: 1988-05-13
Abstract: PURPOSE:To measure a light waveform with high sensitivity even in a extremely thin light range by providing an optical amplifier which amplifies light to be measured and a photodetector composed of a streak tube having a photoelectric surface where the amplified light is incident. CONSTITUTION:The light to be measured is amplified by the optical amplifier 50, then made incident on the photoelectric surface 14 of the streak tube 13 through a lens 12. Then the light is converted into an electron image, which is inputted to a microchannel plate MCP 24. At this time, a fast saw-tooth wave is applied to a deflecting electrode 22 from a single sweep circuit 72, so an electron beam is swept vertically downward to reach the MCP 24. The MCP 24 multiplies the electron image, which is converted by a fluorescent screen 26 into an optical image to display an image corresponding to a streak image or time variation in the intensity of a signal to be measured on a display device 29 through an image pickup device 28. Consequently, part of a fast repetitive phenomenon or continuous phenomenon is extracted and measured with high sensitivity and high time resolution.

Abstract: PURPOSE:To obtain a resonance circuit or the filter which features a wide range  and low loss by increasing the electricity-machine coupling coefficient through alteration of the ratio between the electrode width and the electrode pitch and the decreasing the solid wave component which is excited by the electrode. CONSTITUTION:The piezoelectric surface slide wave is generated or reverse-converted on the substrate via elastic substrate 2-1 featuring the piezoelectric property and at least one pair of electrode 2-31 and 2-32 groups of the cross conductor structure. And the reflective system such as the cut ends, reed screen type electrode 2-2 group, stripe-type groove group and others are located to both sides of the electrode group. Thus, the surface slide wave is resonated through such constitution. Furthermore, the surface slide wave featuring a reflective resonance is combined to other roller-screen type electrode group. In this case, R>0.5 is satisfied for ratio R between pitch P from a center of the reed screen type electrode group to the center of the adjacent electrodes and width l of each electrode finger. As a result, a resosnace circuit or filter can be obtained with a wide range and low loss.
